Question

6x - 6y=42
7x+6y=-48

Answer 1

now add both equations...

Answer 2

you left with:
13x=-6
can you solve for x?

Answer 3

wait does -6 equal x?

Answer 4

no
if you add 1 & 2 :
6x+7x = 42-48 (6y will cancel out)

Answer 5

if 13x=-6
x=-6/13
right?

Answer 6

sooo?.... is that a fraction -6/13
what is y?

Answer 7

I NEED HELP =(

Answer 8

now, you put the value of x in any original equation, let's say 1st...

Answer 9

6x-6y=42 divide both sides by 6:
x-y=7

Answer 10

so i divide 6 by 6?

Answer 11

x=-6/13,so
y=x-7=-6/13 -7=-97/13

Answer 12

x=6?

Answer 13

this is your solution:
x=-6/13 & y=-97/13
